[QUOTE="J E Custom, post: 1342843, member: 2736"] It is not uncommon for a factory rifle barrel to be reused, It is uncommon to improve the performance very much (It is Possible If) The bolt face and the recoil lugs are squared, the receiver is squared to the bolt centerline, the tenon is set back one thread, the chamber is re cut and head spaced correctly and the usual pillar bedding is done. This process will have a chance to improve the accuracy if the barrel bore is good. 90% of factory chambers are not very true and concentric, so re cutting is about the only chance you have of improving the accuracy and only if the bore is good. All of the other improvements will not show much, if any improvement unless you start with a reasonably good bore. Cost wise, It is cheaper because re cutting the chamber does not take a lot of time and you don't have the cost of a new barrel and all of the machining to install it. When re installing the factory barrel it the same receiver, it does nothing to chase the threads but loosen the fit so it is a step in the wrong direction in my opinion. (The threads are as good as they will ever be). Even though I prefer to re barrel a rifle with a custom barrel, It is possible to true everything up correctly and end up with a better shooting factory rifle because almost everything on a factory needs truing to some point. If Done right, It is a good way to turn a 2 MOA rifle into a 1/2 to 3/4 MOA rifle without spending the money to have a custom barrel installed. It is however some what of a gamble as to how well/much it will improve it. A lot of the success of this procedure depends on the smith and how fussy he is. Just because you buy the best barrel made does not automatically guaranty a 1/4 MOA rifle. The same principals of trueness and workmanship still applies. I have repaired many rifles that supposedly had all of this done, and in many cases it was not. So choose a smith wisely and decide what you want and what you expect when the work is done.
